Super Rich !

[TURBO2]

I have a set of 32# Green Stripe Disc Injectors in my '86 G/N. Other upgrades include Ram Air,K&N Cone filter,70mm T.B.,High Output Fuel pump,Adjustable Fuel Pressure Regulator,Terry Houston 3" Downpipe into Dual 2.5" exhaust.
My BLM is 128 (at idle) but it smells like it's burning super rich! I can turn my fuel pressure down and get my BLM to 150 and it still smells like it is burning super Rich!
I have made my own chips adjusting the injector size but it makes no difference except for the fuel pressure needed for proper BLM. Has anybody run into this problem before? Thanks in advance,Curt.

Do you have any type of scantool data at idle? Does it always seems rich at idle, even when completely warmed up?

Yes, Both Scanmaster & Turbolink say I have good BLM & O2 Sensor (brand new) is working. The only strange thing I've found is that the IAC readings are all within spec UNTIL the engine is completely warmed up (i.e. 20-30 mins.). Then the IAC counts dop off to "0" at idle! I have 3 IAC's, one of them brand new,and they all do the same thing.

Sound like maybe EGR valve
